Anti-friction alloy



UNITED STATES PATENT ()EEIoE SAMUEL SINGLEY, OF NEW YORK, N. Y., ASSIGNOR TO THE MAGNOLIA ANTI-FRICTION METAL COMPANY, OF NEW YORK.

ANTI-FRICTION ALLOY.

SPECIFICATION forming part of Letters Patent No. 429,157, dated June 3, 1890.

Application filed June 22, 1889. Serial No. 315,238. (Specimens) To all whom it may concern.-

Be it known that I, SAMUEL SINGLEY, of the city, county, and State of New York, have invented a new and Improved Anti-Friction Alloy, of which the following is a specification.

My composition consists of the following metals, in the proportions substantially as stated:

Lead. 80 pounds. Antimony 15 Tin 5 Bismuth i Silver The lead, when molten, I prefer to cleanse by the application of sufficient sal-ammoniac by adding four to eight ounces of the sal-amnioniac, mixing thoroughly, keeping the molten mass stirred, and removing the scum and dross as it rises; and I also prefer to treat the lead and antimony with sufficient powdered graphite to cover the molten mass, stirring repeatedly, as I have found such treatment to produce better results. If the lead is pure or has been previously cleansed, the sal-amm0- niac may be omitted.

That I claim, and wish to secure by Letters Patent of the United States is The composition of matter to be used for anti-friction purposes, consisting of lead, a11- timony, tin,bismuth, and silver, substantially as described.
